bad news - most shoe companies don't make a shoe for supinators, they class them in with the neutral shoes as the supinator is a bit of a rare breed! but go for a flexible shoe and probably don't run too much in the supernova control and 1080s as you are right, they are for overpronators. Also the more curved the last is of the shoe, the more it encourages the foot to pronate (which is why motion control shoes are dead straight lasted, by the way!)
some neutral shoes are better than others, I would try mizuno neutral shoes in particular if I was you as the wave and low profile of the shoe makes them stable for mild overpronators and also mild supinators. The wave rider, creation and mustang are the mizuno neutral shoes.
it would be worth trying the adidas supernova cushion/response (an old shoe, still good!) and asics cumulus/kumo/preleus (old version of the kumo), if you have gotten on well with the fit of the stability versions of these shoes. New Balance and Saucony also are good makes with quality neutral shoes
Possibly try the Pegasus, but it might be too unstable for you as it is totally designed around the idea that the runner wearing the shoe is efficient and very neutral. Reebok and Puma may not give you the cushioning for the mileage you need.
No idea about Brooks, sorry!
what brands have I missed out?
